I can't seem to add skill points or ability points using the trainer for this game. Everything else works fine but these (as far as I can tell). Even after reading the Notes, these two features don't seem to work.
I'm just going to assume you checked if you are using the correct version. After pressing the corresponding Numpad key, it tells you 'activated'? You pressed the key from the Esc menu? Try hitting Esc twice to reload the menu, it should give you a 'Level up' option now.
